Final answer:
The answer is Marks, and residues; they are left on tools during manufacture or use, allowing forensic scientists to link crime scene evidence with suspect possessions.
Step-by-step explanation:
The correct answer is C) Marks, residues. Certain marks or residues may be left on a tool when it is made or used. These identifiers can be crucial during a forensic investigation when trying to find matches between evidence at a crime scene and objects discovered at a suspect's home. Forensic scientists analyze such traces, which could include the unique patterns left by a tool on a surface, or material residues that might be transferred during the use of the tool. For example, if a weapon is used, it could leave distinct cuts or impressions on a victim or surfaces.
Forensic science techniques such as DNA fingerprinting, RFLP analysis, and the study of tool marks in varied materials provide the necessary evidence to link criminal activity to the tools and objects owned by suspects. This intersection of science and legal investigation is vital for establishing connections between evidence and suspects thereby enabling the legal system to function effectively.
